# UAParser.js

JavaScript library to detect Browser, Engine, OS, CPU, and Device type/model from User-Agent data with relatively small footprint (~17KB minified, ~6KB gzipped) that can be used either in browser (client-side) or node.js (server-side).

# Documentation
### UAParser([user-agent][,extensions])
typeof `user-agent` "string".

typeof `extensions` "array".

In The Browser environment you dont need to pass the user-agent string to the function, you can just call the funtion and it should automatically get the string from the `window.navigator.userAgent`, but that is not the case in nodejs. The user-agent string must be passed in nodejs for the function to work.
Usually you can find the user agent in:
`request.headers["user-agent"]`.


## Constructor
When you call `UAParser` with the `new` keyword `UAParser` will return a new instance with an empty result object, you have to call one of the available methods to get the information from the user-agent string.
Like so:
* `new UAParser([uastring][,extensions])`
```js
let parser = new UAParser("user-agent"); // you need to pass the user-agent for nodejs
console.log(parser); // {}
let parserResults = parser.getResult();
console.log(parserResults);
/** {
  "ua": "",
  "browser": {},
  "engine": {},
  "os": {},
  "device": {},
  "cpu": {}
} */
```

When you call UAParser without the `new` keyword, it will automatically call `getResult()` function and return the parsed results.
* `UAParser([uastring][,extensions])`
    * returns result object `{ ua: '', browser: {}, cpu: {}, device: {}, engine: {}, os: {} }`

## Methods

#### Methods table
The methods are self explanatory, here's a small overview on all the available methods:
*  `getResult()` - returns all function object calls, user-agent string, browser info, cpu, device, engine, os:
`{ ua: '', browser: {}, cpu: {}, device: {}, engine: {}, os: {} }`.

 *  `getBrowser()`      - returns the browser name and version.
 *  `getDevice()`       - returns the device model, type, vendor.
 *  `getEngine()`       - returns the current browser engine name and version.
 *  `getOS()`           - returns the running operating system name and version.
 *  `getCPU()`          - returns CPU architectural design name.
 *  `getUA()`           - returns the user-agent string.
 *  `setUA(user-agent)` - set a custom user-agent to be parsed.

# Usage

## Using HTML

```html
<!doctype html>
<html>
<head>
<script src="ua-parser.min.js"></script>
<script>

    var parser = new UAParser();
    console.log(parser.getResult());
    /*
        /// This will print an object structured like this:
        {
            ua: "",
            browser: {
                name: "",
                version: "",
                major: "" //@deprecated
            },
            engine: {
                name: "",
                version: ""
            },
            os: {
                name: "",
                version: ""
            },
            device: {
                model: "",
                type: "",
                vendor: ""
            },
            cpu: {
                architecture: ""
            }
        }
    */
    // Default result depends on current window.navigator.userAgent value

    // Now let's try a custom user-agent string as an example
    var uastring1 = "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.2 (KHTML, like Gecko) Ubuntu/11.10 Chromium/15.0.874.106 Chrome/15.0.874.106 Safari/535.2";
    parser.setUA(uastring1);
    var result = parser.getResult();
    // You can also use UAParser constructor directly without having to create an instance:
    // var result = UAParser(uastring1);

    console.log(result.browser);        // {name: "Chromium", version: "15.0.874.106"}
    console.log(result.device);         // {model: undefined, type: undefined, vendor: undefined}
    console.log(result.os);             // {name: "Ubuntu", version: "11.10"}
    console.log(result.os.version);     // "11.10"
    console.log(result.engine.name);    // "WebKit"
    console.log(result.cpu.architecture);   // "amd64"

    // Do some other tests
    var uastring2 = "Mozilla/5.0 (compatible; Konqueror/4.1; OpenBSD) KHTML/4.1.4 (like Gecko)";
    console.log(parser.setUA(uastring2).getBrowser().name); // "Konqueror"
    console.log(parser.getOS());                            // {name: "OpenBSD", version: undefined}
    console.log(parser.getEngine());                        // {name: "KHTML", version: "4.1.4"}

    var uastring3 = 'Mozilla/5.0 (PlayBook; U; RIM Tablet OS 1.0.0; en-US) AppleWebKit/534.11 (KHTML, like Gecko) Version/7.1.0.7 Safari/534.11';
    console.log(parser.setUA(uastring3).getDevice().model); // "PlayBook"
    console.log(parser.getOS())                             // {name: "RIM Tablet OS", version: "1.0.0"}
    console.log(parser.getBrowser().name);                  // "Safari"

</script>
</head>
<body>
</body>
</html>
```

## Using node.js

Note: Device information is not available in the NodeJS environment.

```sh
$ npm install ua-parser-js
```

```js
var http = require('http');
var parser = require('ua-parser-js');

http.createServer(function (req, res) {
    // get user-agent header
    var ua = parser(req.headers['user-agent']);
    // write the result as response
    res.end(JSON.stringify(ua, null, '  '));
})
.listen(1337, '127.0.0.1');

console.log('Server running at http://127.0.0.1:1337/');
```

## Using TypeScript

```sh
$ npm install --save @types/ua-parser-js
# Download TS type definition from DefinitelyTyped repository:
# https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/ua-parser-js
```

## Using jQuery/Zepto ($.ua)

Although written in vanilla js, this library will automatically detect if jQuery/Zepto is present and create `$.ua` object (with values based on its User-Agent) along with `window.UAParser` constructor. To get/set user-agent you can use: `$.ua.get()` / `$.ua.set(uastring)`.

```js
// Say we are in a browser with default user-agent: 'Mozilla/5.0 (Linux; U; Android 2.3.4; en-us; Sprint APA7373KT Build/GRJ22) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0':

// Get the details
console.log($.ua.device);           // {vendor: "HTC", model: "Evo Shift 4G", type: "mobile"}
console.log($.ua.os);               // {name: "Android", version: "2.3.4"}
console.log($.ua.os.name);          // "Android"
console.log($.ua.get());            // "Mozilla/5.0 (Linux; U; Android 2.3.4; en-us; Sprint APA7373KT Build/GRJ22) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0"

// Now lets try to reset to another custom user-agent
$.ua.set('Mozilla/5.0 (Linux; U; Android 3.0.1; en-us; Xoom Build/HWI69) AppleWebKit/534.13 (KHTML, like Gecko) Version/4.0 Safari/534.13');

// Test again
console.log($.ua.browser.name);     // "Safari"
console.log($.ua.engine.name);      // "Webkit"
console.log($.ua.device);           // {vendor: "Motorola", model: "Xoom", type: "tablet"}
console.log(parseInt($.ua.browser.version.split('.')[0], 10));  // 4

// Add class to <body> tag
// <body class="ua-browser-safari ua-devicetype-tablet">
$('body').addClass('ua-browser-' + $.ua.browser.name + ' ua-devicetype-' + $.ua.device.type);
```

## Using Extension

* `UAParser([uastring,] extensions)`

```js
// Example:
var myOwnListOfBrowsers = [
    [/(mybrowser)\/([\w\.]+)/i], [UAParser.BROWSER.NAME, UAParser.BROWSER.VERSION]
];
var myParser = new UAParser({ browser: myOwnListOfBrowsers });
var myUA = 'Mozilla/5.0 MyBrowser/1.3';
console.log(myParser.setUA(myUA).getBrowser());  // {name: "MyBrowser", version: "1.3"}
```
